Adnoc Gas, the natural gas processing business of Abu Dhabi National Oil Company (Adnoc Group), has awarded contracts for two key packages of its project to upgrade its sales gas pipeline network across the UAE.

The total value of the two engineering, procurement and construction (EPC) contracts for the project, also known as Estidama, is estimated to be $1.34bn, Adnoc Group said in a statement on 3 July.

UK-headquartered Petrofac has been awarded the EPC contract for package 2 of the Estidama project. Package 2 is understood to be worth $720m, sources told MEED.

A consortium of Abu Dhabi’s National Petroleum Construction Company (NPCC) and Lebanon-headquartered CAT Group has won Estidama package 3, which is valued at approximately $630m, according to sources.

The new pipeline will extend Adnoc Gas’ existing 3,200-kilometre pipeline network to over 3,500km, enabling the transportation of higher volumes of natural gas to customers in the Northern Emirates of the UAE.

“This strategic pipeline extension will drive further growth for Adnoc Gas as it continues to supply sustainable gas supplies in the UAE in support of the company’s strategy to increase its market share and enhance its customer base,” Adnoc said in its statement.

Over 70 per cent of the contracts’ value is expected to flow back into the UAE economy under Adnoc Group’s In-Country Value (ICV) localisation scheme, Adnoc added.

Key Estidama packages

Adnoc Gas Processing, now part of Adnoc Gas, initially intended to issue separate EPC tenders for packages 2 and 5. However, it tendered these as a combined job in June last year. Contractors submitted technical bids for these packages in August 2022.

Eventually, Adnoc Gas divided the scope of work on combined packages 2 and 5, MEED reported in February this year.

Following the revision of the scope of work, Estidama package 2 broadly involves building a new facility at the KP-30 location of the Habshan gas compressor plant (HGCP) and installing three variable frequency drive motor-driven compressors.

Adnoc Gas received technical proposals for Estidama package 2 on 24 February. Contractors submitted commercial bids by 27 March.

Along with Petrofac, the following contractors, among others, are understood to have submitted commercial bids for Estidama package 2:

Package 5 is expected to be tendered separately to contractors as part of a planned second phase of the sales gas pipeline upgrade project.

Adnoc Gas issued the main tender for Estidama package 3 in late June last year.

Contractors submitted technical bids for the package in August 2022, while commercial bids were submitted by 21 November.

MEED previously reported that Italy-headquartered Arkad was the lowest bidder for package 3, with a quotation of about $590m. A source close to the project said that following months of “intense negotiations, due diligence processes and evaluation of project delivery capabilities”, Adnoc Gas picked the consortium of NPCC and CAT for the package.

The scope of work on package 3 covers the installation of new gas pipelines from the Habshan complex to the HGCP, and from the HGCP to the Sweihan customer receipt, along with associated facilities.

Sales gas pipeline project packages

Erstwhile Adnoc Gas Processing, now consolidated into Adnoc Gas, initially divided the EPC work on its estimated $2bn sales gas pipeline network enhancement project into seven main packages.

China Petroleum Pipeline Engineering performed the Estidama project’s front-end engineering and design works as part of a contract worth about $6m that Adnoc Gas Processing awarded the Chinese state-owned firm in October 2020.

MEED reported in December 2021 that Abu Dhabi-based contractor Integrated Specialised General Contracting Company (Iscco) had won package 1, which is understood to have a contract value of $18m.

Iscco subcontracted the detailed engineering works on package 1 to the Abu Dhabi branch of Sweden-headquartered consultancy Rejlers.

Adnoc Gas issued the main tender for package 6 and packages 3 and 2+5 in late June last year.

Contractors also submitted technical bids for package 6 in August 2022 and commercial bids by 21 November.

Work on package 6 entails the installation of a 52-inch, 74km pipeline from Sweihan to Al-Shuwaib in Abu Dhabi and building two block valve stations.

Adnoc Gas combined the scope of work on packages 4 and 7, and issued the main tender in November last year.

Contractors submitted technical bids for combined package 4+7 by 27 March. The project operator is yet to call for commercial bids for this package.

The main scope of work on the Estidama combined package 4+7 involves laying a new pipeline from the Al-Shuwaib pig launcher and pig receiver station to the Sajaa gas facility in Sharjah.

The scope also covers building a new gas pipeline between BVS-2/KP28.7 in Abu Dhabi to Dubai’s Margham gas facility to meet increased gas demand from Adnoc Gas Processing’s customer Dubai Supply Authority (Dusup).

“Up to a dozen contractors are likely to have submitted technical bids for [combined package] 4+7,” one source said.

  • Dubai extends bid deadline for Jebel Ali drainage project

    2 October 2025

     

    Dubai Municipality has extended the bid deadline for a stormwater drainage system in Jebel Ali and the surrounding areas.

    The new deadline is 16 October, a source close to the project told MEED.

    The project covers approximately 27 kilometres of stormwater network and will serve major transport routes, including Sheikh Zayed Road and Al-Jamayel Road.

    The bid submission date for the tender, listed as TF-05-C1, was initially 2 October.

    Works include the installation of pipes ranging from 600 millimetres to 3,500 millimetres, construction of a high-capacity pump station with a capacity of 10 cubic metres a second, and development of open channels and catch basins. The system will be integrated with existing infrastructure.

    Dubai Municipality said the project is intended to manage runoff efficiently, improve road network reliability during storms, and support ongoing and future development in the Jebel Ali area.

    The scheme is being procured by the municipality’s Sewerage and Recycled Water Projects Department as part of the Tasreef programme.

    The latest tender follows a string of recent drainage and stormwater tenders by the municipality.

    Bidding is ongoing for a separate project to develop a stormwater pond, evacuation line and pumping station, including a drainage system along the Dubai-Al-Ain road.

    The bid submission date for this tender, listed under RFQ 229910, was moved to 9 October.

    The initial deadline was 25 September.

  • Riyadh accelerates towards Vision 2030

    2 October 2025

    In April 2016, Crown Prince Mohammed Bin Salman unveiled Vision 2030, a bold blueprint to transform Saudi Arabia’s economy and society. Nearly a decade later, the kingdom is not only on track but has exceeded several key milestones, reshaped its global reputation and unlocked unprecedented investment opportunities.

    At the heart of Vision 2030 are the flagship gigaprojects that have moved from concept to construction. In 2024 alone, gigaproject contracts exceeded $25bn, contributing to a record $154bn in total awards. In the first half of 2025, a total of $25.7bn was awarded – approximately $44.2bn less than the contracts awarded in the first half of 2024.

    The slowdown in activity levels is most acute in the Saudi gigaprojects programme. After growing exponentially each year up to 2023, awards on the programme declined in 2024 and have collapsed almost completely this year as the market transitions to a new phase focused on delivering high-profile international events.

    Saudi Arabia’s transformation is not limited to its headline-grabbing mega developments – key sectors across the economy are also booming.

    In the oil and gas sector, Saudi Aramco is investing heavily in oil-to-chemical complexes and unconventional gas resources, reinforcing the country’s energy dominance. In power, the kingdom is aggressively expanding its renewable energy capacity, aiming to significantly increase the share of renewables in total power generation. The water sector is seeing major infrastructure investment, with over $15bn in contracts awarded in 2024 alone, and a further $7.9bn already committed in 2025 to desalination, treatment and pipeline projects.

    In housing, the National Housing Company is spearheading efforts to deliver 500,000 affordable homes to meet growing demand. Meanwhile, airports in Riyadh and Jeddah are undergoing substantial upgrades valued at $70bn, reflecting Saudi Arabia’s ambition to become a global transport and logistics hub.

    Reforms include public-private partnership (PPP) frameworks to attract private capital

    Strategic shifts

    With a $1.5tn project pipeline, Saudi Arabia faces growing pains: cost inflation, supply chain bottlenecks and workforce constraints. 

    To address these, Riyadh is encouraging international contractors to enter the market; developing super-contractors through joint ventures; and restructuring procurement to favour partnerships over traditional contracting.

  • PPP success should be carefully managed

    2 October 2025

    Commentary
    Colin Foreman
    Editor

    Read the October issue of MEED Business Review

    At first glance, it is the same old story for public-private partnerships (PPPs). National visions require billions of dollars of infrastructure spending, while at the same time government budgets are under pressure.

    Those twin pressures have not always produced successful PPPs outside the traditional power and water sectors in the region. Results have been mixed by sector and country.

    This time around, it is different. While national visions remain as ambitious as ever and state budgets are strained, there has been a shift in mindset as governments realise that PPPs offer more than just an opportunity to get infrastructure delivered for free. 

    The shift has come from the top as leaders seeks to modernise their economies with a thriving private sector. This reduces the state’s capital expenditure burden, while also giving the private sector an opportunity to operate an asset more efficiently for a profit. 

    With buy-in from the highest levels of government, there have been legislative changes and new entities formed to help make PPPs a success.

    These changes have enabled a series of pathfinder projects across the region in recent years that demonstrate that the model does work and even offers benefits that may not have been initially envisaged – such as increased school attendance at PPP schools in Saudi Arabia. 

    As the region now looks to build on that success, there is a risk that governments could overload what is still a nascent market. The capacity to deliver PPPs remains limited, and while it is growing, it is not expanding as quickly as the project pipeline. 

    Governments should ensure that projects are phased with market capacity in mind. If they do not, the danger is the market will collapse under its own weight, as projects may not be competitively tendered, could fail to proceed and may undermine the confidence built up in recent years.

  • Consortiums form for UAE high-speed rail

    2 October 2025

     

    Register for MEED’s 14-day trial access 

    Contractors are forming joint ventures to bid for upcoming design-and-build work packages for the UAE’s high-speed railway (HSR) project.

    The UAE’s Etihad Rail issued the tender for the contract on 10 January, with submissions due on 15 October.

    MEED understands that the group formations for the civil works packages are as follows:

    • Limak / Dogus / Ozkar (Turkiye) – Dubai section
    • NPC / Trojan Tunneling / Kalyon / China State (UAE/UAE/Turkiye/China) – Dubai and Abu Dhabi section
    • WeBuild / Tristar (Italy/UAE) – Abu Dhabi section
    • L&T / China Harbour / Hilalco / Wade Adams (India/China/local/local) – Dubai and Abu Dhabi
    • China Civil Engineering Construction Corporation (China) – Dubai and Abu Dhabi
    • China Railway Engineering Corporation (China) – Dubai section
    • China Railway Engineering Corporation / WBG (China/local) – Abu Dhabi

    French engineering firm Systra is the designer for the Limak-led consortium.

    US-based firm Jacobs is the designer for the NPC group.

    A joint venture of Systra and US-based Aecom is the designer for the WeBuild group.

    French engineering firm Egis and Malaysia’s Surbana Jurong are the designers for the L&T-led consortium.

    Switzerland’s ARX is working with China Civil Engineering Construction Corporation as its designer.

    Chinese firm China Railway Eryuan Engineering Group is working with China Railway Engineering Corporation as its lead designer for both sections of the project.

    Teams are also forming for the systems package. These are:

    • Siemens / Rowad / Salcef (Germany/Egypt/Italy)
    • Hitachi / Orascom (Japan/Egypt)
    • Alstom / L&T (France/India)
    • CRRC (China)
    • Hyundai Rotem / Posco (South Korea)
    • Talgo / Hassan Allam (Spain/Egypt)
    • CAF (Spain)

    The design speed of the trains running on the UAE’s HSR network will be 350 kilometres an hour (km/h) and the operating speed will be 320km/h, as MEED reported last year.

    The proposed HSR programme will be constructed in four phases, gradually adding further connectivity to other areas within the UAE.

    The first phase involves the construction of a railway line connecting Abu Dhabi and Dubai, which is expected to be operational by 2030.

    The second phase will involve the development of an inner-city railway network with 10 stations within the city of Abu Dhabi.

    The third phase of the railway network involves the construction of a connection between Abu Dhabi and Al-Ain.

    The fourth phase involves the development of an inter-emirate connection between Dubai and Sharjah.

    The 150km first phase of the HSR will stretch from the Al-Zahiyah area of Abu Dhabi to Al-Jaddaf in Dubai.

    The project’s civil works have been split into two packages – Abu Dhabi and Dubai – comprising four sections. The scope of these sections includes:

    • Phase 1A: Al-Zahiyah to Yas Island (23.5km) 
    • Phase 1B: Yas Island to the border of Abu Dhabi/Dubai (64.2km)
    • Phase 1C: Abu Dhabi/Dubai border to Al-Jaddaf (52.1km)
    • Phase 1D: Abu Dhabi airport delta junction and connection with Abu Dhabi airport station (9.2km)

    The rail line will have five stations: Al-Zahiyah (ADT), Saadiyat Island (ADS), Yas Island (YAS), Abu Dhabi airport (AUH) and Al-Jaddaf (DJD).

    The ADT, AUH and DJD stations will be underground, while ADS will be elevated and YAS will be at grade.

    The overall construction package also includes provisions for the rolling stock, railway systems and two maintenance depots.

    The high-speed project will slash journey times between the UAE’s two largest cities and economic centres. The journey time between the YAS and DJD stations will be 30 minutes.

    Preliminary site testing works have begun. Dubai-based Matcon Testing Laboratory and Abu Dhabi’s Engineering & Research International are conducting drilling tests to ascertain the ground conditions in areas through which the HSR will pass. 

    Spanish engineering firms Sener and Ineco are the project’s engineering consultants.

  • Iraq aims to double oil flows through export pipeline

    2 October 2025

    Iraq aims to more than double oil flows through the recently reopened Iraq-Turkiye Pipeline (ITP) before the end of the year, according to the Iraqi state oil marketing company Somo.

    Somo aims to transport between 400,000 and 500,000 barrels a day (b/d) by 2026, says Somo spokesperson Rikan Kareem.

    Pipeline flows were running at 150,000-160,000 b/d on 29 September after reopening on 27 September.

    The oil tanker Vallesina is expected to load 700,000 barrels of Iraqi Kurdistan crude oil at Turkiye’s Ceyhan port, becoming the first tanker to load Iraqi Kurdistan crude in more than two and a half years.

    Since oil flows restarted to Turkiye from Iraqi Kurdistan on 27 September, stakeholder sentiment has improved about the outlook for the oil sector in northern Iraq.

    The oil pipeline shutdown, which began two and a half years ago, weighed heavily on the region, costing tens of billions of dollars in lost revenues, according to the Association of the Petroleum Industry of Kurdistan (Apikur).

    During this period, numerous oil projects were put on hold and oil smuggling flourished as producers sold cheap crude into the local market.

    The economic strain also led to salary delays for public sector workers and cuts to essential services.

    The pipeline restart came after eight oil companies operating in Iraqi Kurdistan, representing over 90% of production, reached agreements with Baghdad and the Kurdistan Regional Government (KRG) to resume exports.

    Under the terms of the deal, the KRG will deliver the crude to Somo, and an independent trader will handle sales from the Turkish port of Ceyhan using Somo’s official prices.

    The eight oil producers have agreed to accept a temporary price of $16 a barrel until a review by consultancy Wood Mackenzie is completed.

    The consultancy has been contracted by the Iraqi government to assess production and transportation costs for Kurdish oil, and its assessment will inform the final payment rate.

    The final review is expected to lead to a retroactive adjustment of payments.
